python - generating non-html output from google's app engine -

-

i'm trying dynamically generate ical output using max m's icalendar python module , google's app engine. however, when omit boiler plate <html> header , footer tags on output webapp.requesthandler, looks http 200 response added top of file.

when register code:

class calendar(webapp.requesthandler):     def get(self):         self.response.out.write('begin:vcalendar\n')         [...]

with webapp.wsgiapplication, response looks like:

status: 200 ok content-type: text/html; charset=utf-8 cache-control: no-cache expires: fri, 01 jan 1990 00:00:00 gmt content-length: 11133  begin:vcalendar [...]

how omit <html> tags and not http 200 response splatted @ top of page?

webapp , app engine don't care content type return, issue unrelated tag (or lack thereof). have print statement somewhere in code, causing headers sent part of body of response. should never use print in wsgi app - use self.response.out.write in snippet pasted.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
